Utriculofera Hampson

Type species: fuscapex Hampson, Sri Lanka.

Currently this genus contains the two species described below, as listed by Hampson (1900), and a number of New Guinea species added later. Both Oriental species have similar venation, with a full complement from the forewing cell, the branching system being (R3 (R4, R5)), and Rs and M1 stalked in the hindwing, M2 being lost (Fig 4e). The type species has a cup-like structure at the base of the flagellum of the male antenna, as do most of the New Guinea species, but this is lacking in the Bornean endemic, “U.“macroplaga Hampson.

The two Oriental species have very different male genitalia. Those of the type species are distinguished by a very long, slender uncus, reduction of the distal three-quarters of the valve to a needle and, in the abdomen, the presence of small lateral coremata on the third segment (Fig 296). These features are absent from the second Oriental species, which has a setose structure between the valves similar to that seen in the Garudinia complex.

The female genitalia of the type species are delicate, the ductus narrow, with a slight distal expansion into the short neck of the bursa, the corpus of which is spherical and scobinate throughout.
